'-ipplication filed 'May 3, 1922. Serial No. 558,191.

To all whom t ,mC/y concern:

Be it known that l, Louis Dess, a citizen oi the United States, residing at Chicago, in the county ot Cook and State of illinois, hare invented a new and useiul lniproreiuent in lillectric-l'iainp Supports, ot which the following is a specification.

My invention relates to improved means 'tor supporting .the sockets of' incandescent electric-lamp bulbs on table, floor and wall lanip-xtru'es and inother hanging position; and it is fully described and explained in the following specitication and illustrated in the accompanying drawings, in which- Figure l is a broken view in elevation ol a table or floor lainp showing in r improvement, applied to each of a pair or cluster of the lainpsocliets thereof, which are represented respectively by full and dotted illus tration in different positions of adjustment;

Figure 2 is an enlarged broken sectional view showing my improved means for ad justaloly securing the lamp-socket in Figure 3 is a. broken tion, regarded in the direction of the arrow on Fig. 2, illustrating details of construction, and

Figure 4i is an edge-view of the crimped Washer detail shown in each of thev two preceding figures. i

fin incandescent electric-lamp socket of ordinary general construction is shown at 5, that illustrated being oi' the type provided with a chain 'tor operating the usual switch in the soc-:et 'for opening and closing; the lamp-circuit. For sopor-ably connecting; the socket With. any suitable desired support., tor which the socket is preferably provided on its headend with an internally tliroaded neck 3, l provide a nipple 8, shown to "be hollow or tubular and having a threaded end 9 upon' which the socket-neck is. screwed., The opposite end oft the nipple is substantially one-haii3 oi. a spherical body, or oall 1oisected on an angle to provide a shoulder l inclined relative to the axis of the nipple and having a neck l1 extending centrally from the shoulder. .ln the present showinfr, the nipple 8 is represented as rotatably connecting the lamp-socket to a onpshaped head i2 on the upper end oi the standard 'i3 of a lamp-fixture, such asa table-lamp, though my improvement is intended Jfor application `to any other suitable electric-lamp fixture.` The hodv ont this head View, partly in seeconverges at an oblique angle to the axis of the standard. this angle preferably conforming to that ot the shoulder l0, which is by pre-terence one of: 90 degrees.

For rotatably securing' the nipple in place on a hollow head l2. the latter is perforated and a metal washer 141 is inserted in posi tion to register its openingr with that in the head. 'llie central part of the washer is depressed, as shown at 14a, relative to its marginal portion, which is crimped, as represented at. 143 and has a tongue 15 extending;l radially from it to encounter a projection i6 on the inner 'face of the head for arresting rotation oit the nipple (and with it of the socket) at a point somewhat short of 360 degrees. The washer has itsinneredge portion about the depressed section 14 lienty to extend at a rightangle and Jform a collar i7, tor the purpose hereinafter'explained. lVith the Washer in place, the

nippvif-i-neclt ll is inserted through the register openings in theliead and Washer,

when the innerilend of the Aliollovv neck is upset, as by spinning, to extendi it over the ed e ot the neck-hugging collar 17, as shown in 'igs.. 2 and 3,v for securing 'the nipple in place with "he oblique shoulder 10 bearing against the adjacent surface of the head 12;

The socketcarrying nipple may thus bc rotated in either direction to extend the lamp to any desired angle until arrested by the tongue l5 encountering the stop 16, al-` though the showing in Fig. l represents the sockets `to be turned from and to depending positions through only 3.80 degrees of a circle. Because; oi the SO-degree angularY hearing or the shoulder 10, the nipple, 1n its lowerinost posit'iion` hangs perpendicularly, as represented. iii-Fig. 1,' but in turning it the socket (with a lamp attached) passes through an arc of a sphere with the' advantage o1? throwing the `light outwardly in any desired. direction.

To afford sufiicient resistance for holdin the nipple in any Aposition 'to which it, an with it the Washer are turned, but insuicient to obstruct the turning, a detent is provided et i8 (Fig. 2) to project from the inner face oli the head 1Q into engagement with the crimped or shallowly corrugated adjacent surface ot the Washer 14e r As will be understood, in cases Where the clectriolamps are provided in a cluster about a hollow head, such as the head 12,

the electric wires pass through the hollow nipples and head for connecting the several lamps in the lighting circuit; but where a single-lamp .fixture is provided, the nipple 8 is not necessarily tubular, but may be solid, thoug'h it is then desirable that the neck 1l be tubular for upsetting its inner end about the .collar 17.

The threaded end 9 of .thenipple 8, by enabling a socket to be screwed on and un- 'screwed froml a fixture, facilitates its renova] for repairs and for replacement by a socket of the same or other type.

I realize that considerable variation is f possible in the details of construction herein shown and l do not intend to limit my invention theretoexcept as pointed out in the appended claims,v in which it is my intention to claim all the novelty inherent in my invention as broadly as permissible by the state of the art.

I claim:

ectricdamp iixture comprising, in

a vertical standard, a cupshaped member carried by said standard and having an angular wall, an incandescent electric-lamp carrying nipple, and means for connecting said nipple to the wall of said cup-shaped member in simultaneous rotary and vertically' adjustable relation thereto.

2. In combination with an electric-lamp fixture, means for rotatably connecting therewith an incandescent electric-larnp socket, comprising a nipple terminating at one end in a neck extending through an opening in said ixturc, a washer secured about the inner end of said neck, and an oblique shouider on the nipple bearing against the adjacent surface of said iixture.

3. In combination with an electric-lamp fixture, means for adjustably connecting therewith an incandescent electric-lamp socket, comprising a nipple terminating at one end in a neck extending through an 46 opening in said fixture, an oblique shoulder on the nipple from which the neck extends, to bear against the adjacent surface of said fixture, and a washer about and having a collar surrounding the inner end of the neck 56 which is upset to extend over the edge of the collar for rotatably securing the nipple and collar in place. Y

4. In combination with an electric-lamp fixture, means for adjustably connecting 5t therewith an incandescent electric-lamp socket, comprising a nipple terminating al one end in a neck extending through an opening in said fixture, an oblique shoulder on the nipple from which theneck extends, 60 to bear against the adjacent surface of said ix ure, a corrugated washer having a collar surroundin l the inner end of the neck which is upset to extend over the edge of the collar for rotatably securing the nipple and -collar 65 in place, a tongue rejecting from the Washer, a stop on said xtui`v projecting into the path of the tongue, anda detent on said fixture engaging the corrugated surface. of the washer.

5. In combination with an' electric-lamp fixture, means `for adjustably connecting, therewith an incandescent electric-lamp socket, comprising a nipple terminating at one end in a neck extendin through an 75 opening in said fixture, an ob ique shoulder on the nipple from which the neck extends, to bear against the adjacent surface of said fixture, a corrugated washer having a collar surrounding the inner end of the neck which 8G is upset to extend over the edge of the collar for rotatably securing the nipple and collal# in place, a tongue projecting from the a stop on said fixture projecting washer, and into the path of the tongue.
